Hi this is Jon on behalf of Expert Village in this video clip we would be making our permanent shelf. First off we need to choose a piece of lumber now these are some scrap pieces that I have left from my sheet of plywood. So I just need to pick on that is the correct measurement so I can cut it down to size. First we are going to rip it to 21 13/16. Then we use a table saw and rip to 9 inches. Then we are going to make some trim out a piece of scrap oak. Then I'm going to size it down by using a planer. Then I cut the length, then we glue it, clamp it, and pin nail it.
